Boiler replacement and new heating system upgrades

Boiler replacement is not simply swapping one box for another. The correct boiler, location and system arrangement depends on the property, existing pipework, hot water demand, flue route, condensate route, gas supply, controls, water quality and current manufacturer instructions.

NC Gas Services carries out a proper survey before recommending a replacement or upgrade. Sometimes a boiler cannot safely or legally be installed in the same position as the old appliance because flue clearances, ventilation, condensate disposal, gas pipe sizing or manufacturer requirements have changed.

Survey considerations

  • Gas Safe and Building Regulations requirements.
  • Manufacturer installation instructions for the proposed boiler.
  • Flue route, terminal clearances and plume management.
  • Gas supply sizing and pipework suitability.
  • System water condition, flushing, inhibitor and magnetic filter protection.
  • Radiator and pipework condition, hot water demand and controls.
  • Future access for servicing and maintenance.

Why correct installation matters

A boiler warranty is only useful if the appliance is installed, commissioned and serviced correctly. Incorrect pipe sizing, poor system cleaning, unsuitable flue arrangement, poor condensate installation or missed commissioning details can create reliability issues and may affect warranty support.

Survey fee

Survey work is chargeable because the checks and planning take time. Where agreed, the survey fee can be deducted from the final installation cost if you proceed with the quoted installation.
